Overview
Ply is a small flying organism documented in Artaria, Cataris, and Dairon on ZDR. Its record is visually specific: a pale body carried by broad membrane wings, a large eye-like head, and a thin barbed tail. These features provide a reliable identification basis even when a sighting is brief.
Available observations support sustained flight and a close approach in which the head and tail are directed toward the same space. That makes Ply relevant to route awareness in an enclosed ZDR passage, but it does not establish that the animal is a major threat, a vent specialist, or a migratory species.
The archive does not presently support an account of its feeding, nest construction, reproductive cycle, or relationship to other corridor fauna. Such gaps should remain visible. A small organism can be worth indexing because it is recognizable and repeatedly encountered, not because it has been assigned a fictional ecological role.
Identification And Flight Record
Ply's wing membranes create a distinct silhouette against hard surfaces and enclosed ceilings. The eye-like head is an additional field marker, while the long tail should be recorded separately from a trailing cable, root, or debris strand in poor visibility.
Reports should distinguish a direct observation from an inferred approach. The record supports airborne movement and visible body orientation; it does not prove target selection, pack coordination, or a specialized attack pattern. Note direction, height, and route geometry without turning one pass into a complete behavior model.
ZDR Comparison Records
ZDR supplies the shared setting for Ply, while Blindfly, Dropter, and Sharpaw provide useful comparison points among the archive's other small aerial forms. Similar flight space does not establish shared feeding or lineage.
The X Parasite record remains relevant whenever altered ZDR life is encountered, but baseline Ply observations should not be rewritten as X material without specific evidence of a transformed specimen.
